Detailed description of the invention

[Field of Invention]

The present invention relates to a transfer printing method for printing a cellulose fiber product or a product containing cellulose fiber by a thermal transfer method. More specifically, the present invention applies a transfer paper printed with an ink containing a sublimable disperse dye to a cellulose fiber product or a product containing cellulose fiber, which is printed by a thermal transfer method, thereby printing a cellulose fiber printing material having excellent touch and washing fastness. It relates to a method for producing the.

Background of the Invention and Prior Art

Cellulose fibers are usually made of vegetable natural fibers and fibers made from them, and representative examples thereof include cotton fibers, hemp fibers, and rayon. Cellulose fibers usually form a yarn, a woven fabric or a knit fabric. Cellulose fibers may also be used in combination with other synthetic fibers. Most representative examples are used with synthetic fibers such as polyester. Fiber products in which synthetic fibers are mixed with the cellulose fibers, i.e., containing cellulose fibers, exist in the form of blended yarns, blended fabrics, teaching cloths or interwovens thereof.

Transfer printing means printing sublimable dye before printing on paper and attaching it to fabric cloth and heating it while pressurizing it. Heat-sublimated dye penetrates inside the fiber, cools and is fixed and becomes dye with high fastness. It is a kind of dyeing method of fiber. This transfer printing method is advantageous in terms of economic efficiency and drainage pollution because only a sublimable dye is used, and thus no adhesive is required and no post-treatment such as water washing after dyeing is required.

The method of transferring printing textile products by sublimable disperse dyes is limited to acetate, polyester and nylon fibers. This is because synthetic fibers such as acetate, polyester, and nylon fibers swell the fibers when heat is applied, and the disperse dye penetrates the fibers and is dyeable by transfer printing.

However, a cellulose fiber or a textile product containing cellulose fiber cannot be applied to a transfer printing method using a disperse dye. The reason for this is that a good dyeing cannot be obtained because the crystallinity of the cellulose fiber is high and the disperse dye is hydrophobic, and thus the affinity with the cellulose fiber is low.

Due to the above properties of cellulose fibers, many studies have been conducted to transfer print cellulose fiber products. Known techniques so far as a method for increasing the dye adhesion of the cellulose fiber resin treatment method. And a swelling agent treatment method, a swelling agent and a crosslinking agent treatment method such as melamine resin or glyoxal resin. However, the printing dyeing of the cellulose fibers by these methods has a disadvantage that the feel is not good, such as the fabric is hard and the wash fastness of the printing, that is, the washing resistance is not good.

The present inventors have recognized the above problems in the method of transfer printing of cellulose fiber products, and can obtain dyeings having good washing fastness and feel by a transfer printing method using a cellulose fiber product or a fiber product containing the same by using a sublimable disperse dye. It is early to develop a way.

It is to provide a transcription printing method.

Hereinafter, the details of the present invention will be described in detail.

Detailed Description of the Invention

The transfer printing method of a cellulose fiber product or a cellulose fiber-containing product according to the present invention is a swelling agent made of polyhydric alcohol or a derivative thereof, and a crosslinking agent made of a polyurethane resin derivative. And padding in a padding mangle with a pretreatment solution consisting of a polyurethane resin catalyst; Drying the padded fibrous product at a temperature of 130 ° C. or less in a second step; In the third step, the transfer paper was pre-printed with a printing ink containing a sublimable disperse dye on the dried fiber product, and then heated and pressurized for 10 to 40 seconds at a temperature of 180 to 230 ° C. and a pressure of 1 kg / cm 2. The sublimable dispersion dye is transferred to the inside of the cellulose fiber.

The pretreatment solution of the first step is composed of a swelling agent made of polyhydric alcohol or a derivative thereof, a crosslinking agent made of a polyurethane resin derivative, and a polyurethane resin catalyst.

Since cellulose fibers and cellulose fiber products have high crystallinity and incompatibility with disperse dyes, when the transfer printing is applied, thermal swelling is not sufficient to infiltrate the disperse dye, so a swelling agent should be used to swell the cellulose fibers. As the swelling agent having a swelling action with respect to cellulose fibers and cellulose fiber products, polyhydric alcohols having a boiling point of 150 ° C or higher and derivatives thereof are preferable.

Examples of swelling agents include ethylene glycol, ethylene glycol monoethyl ether acetate, ethylene glycol monobutyl ether, ethylene glycol monobutyl ether acetate, ethylene glycol isoamyl ether, ethylene glycol monophenyl ether, ethylene glycol monophenyl acetate, ethylene glycol monohexyl Acetate, ethylene glycol monoacetate, ethylene glycol diacetate, ethylene glycol formic acid monoester, ethylene glycol formic acid diester, ethylene glycol acetic acid monoester, methoxy methethanol, diethylene glycol, diethylene glycol monoethyl ether, diethylene glycol mono Ethyl ether acetate, diethylene glycol monobutyl ether, diethylene glycol monobutyl ether acetate, diethylene glycol methylethyl ether, diethylene glycol dimethyl ether, diethylene glycol di Butyl ether, diethylene glycol dibutyl ether, ethylene glycol dibutyl ether, diethylene glycol monoacetate, diethylene glycol diacetate, triethylene glycol, triethylene glycol monomethyl ether, triethylene glycol monoethyl ether, tetra glycol, polyethylene Glycol (molecular weight 200 ~ 600), propylene glycol, propylene glycol monobutyl ether, propylene glycol monoacetate, propylene glycol diacetate, dipropylene glycol, dipropylene glycol monoethyl ether, tetrapropylene glycol monoethyl ether, polypropylene glycol (molecular weight) 400-2000), trimethylene glycol, butanediol, 1-5 pentanediol, octylene glycol, hexylene glycol, glycerin, glycerin monoacetate and the like.

A swelling agent such as ethylene glycol penetrates inside the cellulose fiber to widen the gap between the cellulose fiber molecules, thereby causing the cellulose fiber to swell.

The swelling agent consisting of the polyhydric alcohol and its derivative is used in about 10 to 40% by weight of the pretreatment aqueous solution, and by adding the swelling agent to the pretreatment aqueous solution, the pretreated cellulose fibers are swollen and the transfer printing method can be applied.

The crosslinking agent is composed of a polyurethane resin derivative and is used at 10 to 40% by weight of the pretreatment solution. Polyurethane resin derivatives are cross-linked by the action of polyurethane resin catalyst on cellulose fibers to form a coating on the cellulose fibers to improve the tactile feel and printing resistance of the cellulose fiber products when printing the cellulose fiber products. It improves washing fastness so that the color does not change even after several washings.

The crosslinking agent made of this polyurethane resin derivative is crosslinked at a high temperature (180-230 ° C.) at the time of thermal transfer printing after padding the pretreatment aqueous solution to the cellulose fiber product. That is, as the transfer printing, the disperse dye penetrates inside the cellulose fiber to be dyed, and a crosslinking agent, that is, a polyurethane resin, forms a coating thereon.

In this case, the polyurethane resin catalyst initiates the crosslinking reaction of the polyurethane resin derivative to form a polyurethane resin, and is used as 1 to 4% by weight of the pretreatment solution.

When the pretreatment solution consisting of 10 to 40% by weight of a swelling agent made of polyhydric alcohol or a derivative thereof, 10 to 40% by weight of a crosslinking agent made of a polyurethane resin derivative, and 1 to 4% by weight of a polyurethane resin catalyst is prepared. The aqueous solution is immersed in this pretreatment aqueous solution and then padded in a padding mangle. The cellulose fiber product or the cellulose fiber-containing product, which is padded with a pre-aqueous aqueous solution, swells enough to penetrate the disperse dye during transfer printing and has a high affinity with the disperse dye.

In the second step, the padded cellulose fiber product is dried at a temperature of 130 ° C. or less, wherein the swelling agent composed of polyhydric alcohol and derivatives thereof is absorbed well by the cellulose fiber product and swelled to dry.

The third step is a thermal transfer step, the transfer paper pre-printed with a printing ink containing a sublimable disperse dye on the dried cellulose fiber product is heated for 10-40 seconds at a temperature of 180 ~ 230 ℃ and a pressure of 1kg / ㎠ Pressurizing is a process to allow the sublimable disperse dye of the transfer paper to penetrate into the cellulose fiber. Methods of making transfer papers printed with disperse dyes are well known in the art.

By the thermal transfer process, the disperse dye of the transfer paper is sublimed and condensed into the swelled cellulose fiber sufficiently by the action of the pre-treatment aqueous solution so that both the cellulose fiber product and the cellulose fiber-containing product are uniformly dyed, and the high temperature during thermal transfer (180-230). The film is formed on the cellulose fibers by crosslinking of the polyurethane resin derivative at 占 폚, so that the feel of the printing material is better and the affinity with the disperse dye of the cellulose fiber product is also increased, thereby improving the washing resistance of the printing material.

In addition, in the present invention, the polyurethane resin derivative and the polyurethane resin catalyst are padded again on the heat-transfer-printed cellulose fiber products by the first, second, and third processes, and the fixing treatment is performed for 30 to 90 seconds at a temperature of 160 to 180 ° C. In order to form a film on the cellulose fiber product once more, it is possible to obtain a thermal transfer printing cellulose fiber product having better washing fastness and feel.

By using the transfer printing method as described above of the present invention, a cellulose fiber printing material having good washing fastness of the printing material can be produced, and a transfer printing material having good feel and volume can be obtained.

The present invention may be further embodied by the following examples, which are not intended to limit the protection scope of the present invention, but are described for exemplary purposes.
